Astronomers have discovered a giant Saturn-sized planet orbiting TOI-6894, the tiniest known star to host such a world. This surprising find challenges established theories that small stars lack the material to form giant planets.

Summary

Astronomers have discovered a Saturn-sized planet orbiting the tiny star TOI-6894, a discovery that challenges existing planet formation theories. This giant planet orbiting such a small star, the smallest known to host such a large world, was an unexpected find. The prevailing theory suggests that small stars lack sufficient material in their protoplanetary disks to form gas giants. This discovery prompts reevaluation of planet formation models and suggests the possibility of more giant planets orbiting small stars than previously thought. Further research is needed to understand how this planet formed around TOI-6894.
